Magneto-structural transitions induced at 1.2 K in Ni2MnGa-based Heusler alloys by high magnetic field up to 60 T

The huge decrease of the martensitic transition temperature TM-A with increasing field (up to dTM-A/dH=8.1 K T-1) was observed in all the Co-doped and In-doped Ni50-xCoxMn25+yGa25-y-zInz Heusler alloys at high pulse magneti...

High-field magnetization of UCuGe single crystal

The hexagonal compound UCuGe an antiferromagnet with TN=48 K, exhibits in fields 38-45 T (at 4.2 K), applied along the c axis, a spin-flop transition to a state with a moment of 1.35 .mu..BETA./U. The magnetic susceptibility in ...

High-field magnetization of a DyFe5Al7 single crystal

, two field-induced hysteretic transitions are observed at 30 and 53 T at T = 2 K. The critical field H-cr1 of the first transition depends strongly on temperature, whereas H structure was measured in pulsed fi...

Pressure-driven metal-insulator transition in hematite from dynamical mean-field theory

Combination of the an initio bandstructure and dynamical mean-field theory is used to study simultaneous high-spin low-spin and metal-insulator transtion in hematite (Fe2O3). Comparison to isoelectronic MnO is made. We identify two ...
