Magnetic phase diagram of CrPSand its exchange interaction in contact with NiFe.

The magnetic phase diagram of the two-dimensional van der Waals magnet CrPSand the exchange bias effect of CrPSin contact with NiFe film have been investigated. Based on the magnetic measurements, we figure out the relatively low spin-flop field and spin-flip field for CrPS, both of the spin transition phenomena are strongly affected by the temperature. The perpendicular exchange bias effect is studied in CrPSsingle-crystal flake covered with 5 nm NiFe. Meanwhile, the variation of the cooling field has a great influence on the exchange bias field and coercivity, which is mainly attributed to the competition between the Zeeman energy and the exchange coupling at the interface as well as the formation of the multi-domain state.
