Magnetization Process and Spin-Structure Diagram in Manganese Phosphide Single Crystal

Abstract

Magnetizations in the three main planes of a single crystal of manganese phosphide are measured at 4.2°K. Especially the b-axis magnetizations are studied in detail in the range of magnetic field up to 80 kOe at various temperatures. The screw-spin state of ferromagnetic spin state transforms to the fan state and than to the complete paralell arrangement by the external magnetic field applied along the b axis. From the results obtained, the spin structure diagram is made as a function of temperature and of magnetic field applied along the b axis.
