Probing the Mott Physics in -(BEDT-TTF)X Salts via Thermal Expansion
Mariano de Souza, Lorenz Bartosch
In the field of interacting electron systems the Mott metal-to-insulator (MI) transition represents one of the pivotal issues. The role played by lattice degrees of freedom for the…
Lattice strain accompanying the colossal magnetoresistance effect in EuB
Rudra Sekhar Manna, Pintu Das, Mariano de Souza +4
The coupling of magnetic and electronic degrees of freedom to the crystal lattice in the ferromagnetic semimetal EuB, which exhibits a complex ferromagnetic order and a colossa…
Magneto-elastic couplings in the distorted diamond-chain compound azurite
Pham Thanh Cong, Bernd Wolf, Rudra Sekhar Manna +4
We present results of ultrasonic measurements on a single crystal of the distorted diamond-chain compound azurite Cu(CO)(OH). Pronounced elastic anomalies are obser…
Lattice effects in the quasi-two-dimensional valence-bond-solid Mott insulator EtMeP[Pd(dmit)]
Rudra Sekhar Manna, Mariano de Souza, Reizo Kato +1
The organic charge-transfer salt EtMeP[Pd(dmit)] is a quasi-two-dimensional Mott insulator with localized spins = 1/2 residing on a distorted triangular lattice. He…
Low temperature structural effects in the (TMTSF)PF and AsF Bechgaard salts
P. Foury-Leylekian, S. Petit, I. Mirebeau +6
We present a detailed low-temperature investigation of the statics and dynamics of the anions and methyl groups in the organic conductors (TMTSF)PF and (TMTSF)AsF (…
High-resolution thermal expansion measurements under Helium-gas pressure
Rudra Sekhar Manna, B. Wolf, M. Souza +1
We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4 K 300 K and h…
