文摘
- •
The ternary intermetallic compound DyMn2Si2 is proposed as magnetocaloric material.
- •
Four magnetic phase transitions were identified for DyMn2Si2 at low temperatures.
- •
H >35 kOe favor antiferromagnetic clusters and give rise to exchange bias effect.
- •
Two successive magnetic phase transitions induce a large table like EMC.
