Magnetic properties of the quasi-two-dimensional S = 1/2 Heisenberg antiferromagnet [Cu(pyz)2(HF2)]PF6
E. Cizmar, S. A. Zvyagin, R. Beyer +6
We report on high-field magnetization, specific-heat and electron spin resonance (ESR) studies of the quasi-two-dimensional spin-1/2 Heisenberg antiferromagnet [Cu(pyz)2(HF2)]PF6.…
Interplay of frustration and magnetic field in the two-dimensional quantum antiferromagnet Cu(tn)Cl
A. Orendáčová, E. Čižmár, J. S. Xia +11
Specific heat and ac magnetic susceptibility measurements, spanning low temperatures ( mK) and high magnetic fields ( T), have been performed on a two-dimensi…
THz-range free-electron laser ESR spectroscopy: techniques and applications in high magnetic fields
S. A. Zvyagin, M. Ozerov, E. Čižmár +6
The successful use of picosecond-pulse free-electron-laser (FEL) radiation for the continuous-wave THz-range electron spin resonance (ESR) spectroscopy has been demonstrated. The c…
Origin of magnetic moments in defective TiO2 single crystals
Shengqiang Zhou, E. Cizmar, K. Potzger +7
In this paper we show that ferromagnetism can be induced in pure TiO2 single crystals by oxygen ion irradiation. By combining x-ray diffraction, Raman-scattering, and electron spin…
