Magnetic versus nonmagnetic doping effects on the magnetic ordering in the Haldane chain compound PbNi2V2O8

Andrej Zorko, Denis Arcon, Alexandross Lappas +1

A study of an impurity driven phase-transition into a magnetically ordered state in the spin-liquid Haldane chain compound PbNi2V2O8 is presented. Both, macroscopic magnetization a…

Magnetic Anisotropy of SrCu $_{2}$ (BO $_{3}$ ) $_{2}$ System as Revealed by X-Band ESR

A. Zorko, D. Arčon, H. Kageyama +1

X-band ESR measurements on a single crystal of the highly frustrated SrCu $_{2}$ (BO $_{3}$ ) $_{2}$ system are shown to provide an essential inspection of the magnetic anisotropy present in…
