Strong ferromagnetism at the surface of an antiferromagnet caused by buried magnetic moments
Alla Chikina, Marc Höppner, Silvia Seiro +13
Carrying a large, pure spin magnetic moment of 7 bohr/atom in the half-filled 4f shell, divalent europium is an outstanding element for assembling novel magnetic devices in whic…
Orbital occupancies and the putative jeff = 1/2 groundstate in Ba2IrO4: a combined oxygen K edge XAS and RIXS study
M. Moretti Sala, M. Rossi, S. Boseggia +9
The nature of the electronic groundstate of Ba2IrO4 has been addressed using soft X-ray absorption and inelastic scattering techniques in the vicinity of the oxygen K edge. From th…
Changes of statistical structural fluctuations unveils an early compacted degraded stage of PNS myelin
Nicola Poccia, Gaetano Campi, Alessandro Ricci +4
Degradation of the myelin sheath is a common pathology underlying demyelinating neurological diseases from Multiple Sclerosis to Leukodistrophies. Although large malformations of m…
Distinct magnetic phase transition at the surface of an antiferromagnet
Sean Langridge, Gavin M. Watson, Doon Gibbs +6
In the majority of magnetic systems the surface is required to order at the same temperature as the bulk. In the present study, we report a distinct and unexpected surface magnetic…
Magnetic quantum oscillations in the charge-density-wave state of the organic metals -(BEDT-TTF)MHg(SCN) with M = K and Tl
M. V. Kartsovnik, V. N. Zverev, D. Andres +6
The low-temperature charge-density-wave (CDW) state in the layered organic metals -(BEDT-TTF)MHg(SCN) has been studied by means of the Shubnikov -- de Haas and de Haas -…
System analysis of Force Feedback Microscopy
Mario S Rodrigues, Luca Costa, Joel Chevrier +1
It was shown recently that the Force Feedback Microscope can avoid the jump-to-contact in Atomic force Microscopy even when the cantilevers used are very soft, thus increasing forc…
