“Exchange bias of spring-like domain walls”

Rafael Morales

(UPV/EHU)

The exchange coupling between antiferromagnetic (AFM) and ferromagnetic (FM) materials yields a shift of the hysteresis loop along the magnetic field axis. The magnitude of this shift is known as exchange bias field, Heb.

“Lattice anomalies at the ferroelectric and magnetic transitions in cycloidal Mn0.95Co0.05WO4 and conical Mn0.80Co0.20WO4 multiferroics” 

Irene Urcelay Olabarria

(BCMaterials)

Different types of subtle lattice anomalies (Dl/l ∼ 10−5) are reported in the multiferroic Mn1xCoxWO4 (x = 0.05 and 0.20) compounds coinciding with the successive magnetic transitions below 30 K.
