30 Jan 2017 | | Abstract: | Muon-spin rotation data collected at ambient pressure ($p$) and at $p=2.42$
GPa in MnP were analyzed to check their consistency with various low- and
high-pressure magnetic structures reported in the literature. Our analysis
confirms that in MnP the low-temperature and low-pressure helimagnetic phase is
characterised by an increased value of the average magnetic moment compared to
the high-temperature ferromagnetic phase. An elliptical double-helical
structure with a propagation vector ${f Q}=(0,0,0.117)$, an $a-$axis moment
elongated by approximately 18% and an additional tilt of the rotation plane
towards $c-$direction by $simeq 4-8^{
m o}$ leads to a good agreement between
the theory and the experiment. The analysis of the high-pressure $mu$SR data
reveals that the new magnetic order appearing for pressures exceeding $1.5$ GPa
can not be described by keeping the propagation vector ${f Q} parallel c$.
Even the extreme case -- decoupling the double-helical structure into four
individual helices -- remains inconsistent with the experiment. It is shown
that the high-pressure magnetic phase which is a precursor of superconductivity
is an incommensurate helical state with ${f Q} parallel b$. | | Source: | arXiv, 1701.8699 | | Services: | Forum | Review | PDF | Favorites | |
