The magnetic structure and spin-flop transition in the A-site columnar-ordered quadruple perovskite $TmM n_{3} O_{6}$

A. M. Vibhakar, D. D. Khalyavin, P. Manuel +5

We present the magnetic structure of $TmM n_{3} O_{6}$ , solved via neutron powder diffraction - the first such study of any $R M n_{3} O_{6}$ A-site columnar-ordered quadruple…

Unconventional field-induced spin gap in an $S = 1/2$ chiral staggered chain

J. Liu, S. Kittaka, R. D. Johnson +11

We investigate the low-temperature magnetic properties of the molecule-based chiral spin chain [Cu(pym)(H $_{2}$ O) $_{4}$ ]SiF $_{6} \cdot$ H $_{2}$ O (pym = pyrimidine). Electron-spin resonance,…

Evolution of magneto-orbital order upon B-site electron doping in Na1-xCaxMn7O12 quadruple perovskite manganites

R. D. Johnson, F. Mezzadri, P. Manuel +3

We present the discovery and refinement by neutron powder diffraction of a new magnetic phase in the Na1-xCaxMn7O12 quadruple perovskite phase diagram, which is the incommensurate…
