DESCRIPTION:Speakers: Elisabetta Nocerino (KTH Royal Institute of Technolo
 gy)\nRhenium oxide compounds of the type AReO$_4$ where A is a first-row t
 ransition metal cation\, exhibit interesting electronic properties. Among 
 this family of compounds\, MnReO$_4$ was the first of this kind\, synthesi
 zed with a high-pressure technique at 25 kbar in 1970 **[1]**. It has a wo
 lframite structure where both cations have partially filled d shells\, and
  an anisotropic electrical resistivity that makes it suitable for potentia
 l applications in the development of electrical devices **[2]**. Although 
 this material was already known for several years\, the magnetic propertie
 s of MnReO$_4$ have never been studied in detail. In this work we present 
 the very first investigation of the magnetic nature of the wolframite insu
 lator MnReO$_4$ carried out by muon spin rotation. The aim of the experime
 nt was to clarify the occurrence a static antiferromagnetic order\, and th
 e possibility for the formation of magnetic multipole order at low tempera
 tures\, which is expected due to the lack of an inversion symmetry at the 
 Re6+ site and a strong spin-orbital coupling of its 5d1 electron. The occu
 rrence of the static antiferromagnetic ordering was clearly observed in Mn
 ReO$_4$ and the order parameter of the transition was determined.\n\n**[1]
