The transition-metal based alloy system YNi 4-xCo xSi shows a second-order ferromagnetic-to-paramagnetic transition near room temperature. Here, the magnetic structure, the magnetocaloric properties and the magnetic anisotropy of ...
The increasing energy consumption in buildings due to cooling and heating, accounting for over one-third of the total energy consumption in society, has become a growing concern. Therefore, reducing building energy consumption has become an urgent issue for countries worldwide. W ...
Mn compounds presenting magneto-structural phase transitions are currently intensively studied for their giant magnetocaloric effect; nevertheless, several parameters remain to be further optimized. Here, we explore the Mn(Fe,Ni)(Si,Al) series, which presents two advantages. The ...

(Fe,Co)2(P,Si) rare-earth free permanent magnets

From macroscopic single crystals to submicron-sized particles

While rare-earth magnets exhibit unchallenged hard-magnetic properties, looking for alternatives based on inexpensive elements of non-critical supply remains of utmost interest. Here, we demonstrate that (Fe,Co)2(P,Si) single crystals combine a large magnetocrystalline ...
