The results of studies of Y$_{2}$Ti$_2$O$_7$ single crystals doped with Er$^{3+}$ and Yb$^{3+}$ ions by means of electron paramagnetic resonance (EPR) and dc-magnetometry are reported. EPR signals of the trigonal centers with the…

The discovery of two-dimensional (2D) systems hosting intrinsic long-range magnetic order represents a seminal addition to the rich physical landscape of van der Waals (vdW) materials. CrI3 has emerged as perhaps the most salient example,…

The magnetic properties of single crystalline EuPtGe$_3$, crystallizing in the non-centrosymmetric BaNiSn$_3$-type crystal structure, have been studied by means of magnetisation, electrical resistivity, heat capacity and $^{151}$Eu…
