Area of Science:

• Materials Science
• Condensed Matter Physics
• Nanotechnology

Background:

• Static magnetic properties of nanomaterials, particularly defect-induced magnetism, are a key research area in diluted magnetic semiconductors.
• Dynamic magnetic properties of nanomaterials are often overlooked, especially when their bulk forms are non-magnetic.

Purpose of the Study:

• To investigate the static and dynamic magnetic properties of titanium nitride-carbon (TiN/C) nanocomposites.
• To explore novel electromagnetic resonance phenomena in TiN/C systems.
• To challenge conventional electromagnetic theories and explore simultaneous control of permeability and permittivity.

Main Methods:

• Synthesis and characterization of TiN/C nanocomposites.
• Measurement of static and dynamic magnetic properties.
• Analysis of electromagnetic resonance behavior, including permeability and permittivity.

Main Results:

• TiN/C nanocomposites display static and dynamic magnetic properties with opposing trends.
• Unconventional electromagnetic resonance behavior was observed in the TiN/C systems.
• Permeability and permittivity exhibited similar trends, challenging traditional electromagnetic understanding.

Conclusions:

• TiN/C nanocomposites possess both static and dynamic magnetic properties, contrary to expectations for non-magnetic bulk materials.
• The observed electromagnetic resonance and correlated permeability/permittivity trends offer new insights into nanostructure electromagnetism.
• This research provides a pathway for achieving a balanced permeability and permittivity in a simple system, potentially guiding future nanostructure design.
