Abstract:
The magnetic properties of Gdin polycrystalline GdTewere investigated by magnetization, heat capacity, magnetoresistance, and electron spin resonance (ESR) which all reveal clear indications of a magnetic phase transition atK in their temperature dependencies. The transition displays characters of competing ferromagnetic and antiferromagnetic interactions which is particularly supported by distinct anomalies in the ESR linewidth and intensity, providing a local picture of magnetism at the transition. A pronounced negative magnetoresistance documents a strong coupling between magnetic order and charge transport in the puckered GdTe double layers that form the GdTecrystal structure.

Diamagnetism
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets.

Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...
