文摘
- •
LaFe12B6 is an itinerant-electron antiferromagnet with 0.36 μB/Fe-atom in the ground state.
- •
The metamagnetic transition occurs below and above the Néel temperature.
- •
The kinetic arrest takes place at low temperatures.
- •
The magnetic phase diagram exhibits a critical end point.
- •
Large magnetocaloric effects are obtained due to the metamagnetic transition.
