Nuclear Overhauser Enhancement (NOE)01:06

Nuclear Overhauser Enhancement (NOE)

Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the nuclear Overhauser enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring spin-active...

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...
Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.
Additional Subnuclear Structures02:10

Additional Subnuclear Structures

The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles, paraspeckles, etc. These nuclear...

¹H NMR: Complex Splitting01:13

¹H NMR: Complex Splitting

A proton M that is coupled to a proton X results in doublet signals for M. However, NMR-active nuclei can be simultaneously coupled to more than one nonequivalent nucleus. When M is coupled to a second proton A, such as in styrene oxide, each peak in the doublet is split into another doublet.
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Magnetism

Background:

  • Understanding magnetism in 5d compounds requires identifying superexchange interactions.
  • Double perovskite Y2NiIrO6 (YNIO) is a ferrimagnetic insulator with an Ir4+ 5d Jeff = 1/2 Mott-insulating state at ambient pressure.

Purpose of the Study:

  • To investigate the effects of physical pressure on the magnetic properties of Y2NiIrO6 (YNIO).
  • To elucidate the mechanism of 5d-3d superexchange and guide bond-engineered magnetism in iridate systems.

Main Methods:

  • Experimental study of pressure effects on YNIO up to 17 GPa.
  • Analysis of Ni/Ir-O bond lengths and Ni-O-Ir bond angles under pressure.
  • Comparison with related materials like Sr2IrO4 and La2NiMnO6.

Main Results:

  • Physical pressure increases the Curie temperature of YNIO from 192 K to 243 K.
  • Pressure causes concurrent compression of Ni/Ir-O bonds and Ni-O-Ir angles.
  • Rock-salt ordered Ni-Ir and orthogonal Ni eg-Ir t2g pathways suppress magnetic frustration, unlike in other iridates.

Conclusions:

  • The study establishes a framework for understanding 5d-3d superexchange mechanisms.
  • Lattice distortion robustly maintains the Ni-Ir superexchange pathway in YNIO.
  • Findings guide the engineering of magnetism in iridate-based materials through bond manipulation.
