High field magnetic properties in single crystal Nd3Co

Abstract

Magnetization as a function of field was measured in pulsed fields of up to 40 T at various temperatures along the principal axes of single crystal Nd3Co. Along the a axis we observed metamagnetic transitions at fields of 1.9 and 4.5 T at 4.2 K. We also observed a sharp increase in the magnetic moment in applied fields between 9.5 and 14 T. Along the b axis a metamagnetic transition was observed at a field of 1.5 T at 4.2 K. Along the c axis we observed ferromagnetic behavior. The H–T (magnetic field and temperature) phase diagram was obtained using a superconducting quantum interference device magnetometer.

Irreversible field-induced magnetic phase transitions and properties of Ho3Co

“…The measurements of the magnetization, electrical resistivity and specific heat performed for some R 3 Co compounds on polycrystalline samples [3,4] and on single crystals [5][6][7][8][9][10][11][12][13][14][15], as well as neutron diffraction investigation [16][17][18][19][20], have revealed several anomalous features, which may be summarized as follows:…”

Magnetic structure of the ferromagnetic new ternary silicide Nd5CoSi2

“…For instance, if each site of Co has a magnetic moment of 0.2 µ B , the R B−mag factor increases from 5.2 to 5.5%. The absence of Co magnetic moment was also reported for the binary compound Nd 3 Co [13,21] containing as Nd 5 CoSi 2 a low atomic percentage of Co.…”
