Low temperature magnetic properties of the mineral gaudefroyite
The mineral gaudefroyite contains parallel chains of linked MnO6 octahedra. The Mn magnetic moments order with parallel spins within a given chain at low temperature, but the... -
Is there a hidden Magnetic Order in KxRb2-xV8O16?
KxRb2-xV8O16 are series of hollandite compounds exhibiting a quasi 1D structure. In such systems, the formation of the magnetic ground state originates from a dominant... -
Bose-Einstein Condensation in solid helium confined in porous media
We propose measurements of the Bose-Einstein Condensate (BEC) fraction n0 of solid helium confined in porous media. A superfluid fraction in solid helium in Vycor, in aerogel...
