Abstract
The growth and magnetic properties of Tin Selenide (SnSe) doped with Eu2+ Sn1−xEuxSe (x=2.5%) were investigated. Q-band (34 GHz) electron paramagnetic resonance measurements show that the site symmetry of Eu2+ at 4.2 K is orthorhombic and the Landé factor was determined to be g=1.99±0.01. The exchange coupling between nearest-neighbor (NN) Eu2+ ions was estimated from magnetization and magnetic-susceptibility measurements using a model that takes into account the magnetic contributions of single ions, pairs and triplets. The exchange interaction between Eu2+ nearest neighbors was found to be antiferromagnetic with an estimated average value of Jp/kB=−0.18±0.03 K.
