Structure and Hard Magnetic Properties in Nd2Fe14B-type Compounds

Hydrogenation Effects in UTGe Compounds: Structure and Magnetic Properties

UTGe compounds absorb hydrogen up to 2 H atoms/f.u., which has a dramatic impact on the 5f magnetism. The TC value of UCoGe increases to 50 K. Magnetic susceptibility of spin fluctuator UFeGe markedly increases. For ferromagnetic URhGe only α-hydride could be obtained with moderate increase of TC and spontaneous moment. The α-hydride of UCoGe is surprisingly paramagnetic despite of a small volu...

MAGNETIC PROPERTIES OF THE AuCu3-TYPE Sm-COMPOUNDS

Resistivity, susceptibility, specific heat a d magnetization measurements on single crystals SmPb3, SmPds and SmT13 are performed. The phase transition of the antiferromagnet, SmPb3, is of first order at 5.1 K. SmPda shows an antiferromagnetic ordering at 1.36 K. SmT13 behaves as a ferromagnet with T, =8.6 K. The ground states of sm3+ (J= 512) ions in these Sm-compounds are r s quartets. Recent...

بررسی اثر دما بر خواص مغناطیسی آهنربای سخت نئودمیوم- آهن- بور (Nd2Fe14B) تولید شده به‌روش پرس گرم
