Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of...

Organic semiconductors have been of major interest in recent years. Amplified by the transition from fundamental physics to new commercial products and technologies, this new...

During the past decades, weakly coupled spin cluster systems have attracted much attention due to the possibility of observing concomitantly zero-dimensional quantum and...

Magnetism and superconductivity compete and coexist in many of the high temperature superconductors, and the newly discovered iron arsenides are no exception. Muon-spin rotation...

We have prepared a new family of electron-doped oxypnictides \RFeF\ with the same average Rare Earth radius as that yielding the highest superconducting Tc to date, i.e. the...

We will examine the magnetic and superconducting properties of these two novel superconducting systems using muon spin rotation and relaxation experiments. Stoichiometric LiFeAs...

Molecular ferromagnets offer great potential as they are synthesized at low temperatures and offer the possibility functionalization. Ni(TCNQ)2 is such a molecular ferromagnet,...

SrCo2V2O8 is believed to belong to the same rare universality class as Tomonaga-Luttinger liquids, which may be descrived by the 1D XXZ model. In SrCo2V2O8, this is accomplished...

It is proposed to use ZF and TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions...

The iron-based superconductor LiFeAs exhibits a number of unique features distinguishing it from other materials in its class. As yet, these differences are unexplained. This...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

We propose to use muon spin relaxation to examine the anomalous magnetic phase behaviour of Ba2MnMoO6. This compound shares the frustrated geometry that leads to a valence bond...

BaCu2Ge2O7 is reported to be a one dimensional Heisenberg antiferromagnet, with three dimensional long range order at low temperatures due to small antiferromagnetic...

The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should...

In view of the interesting magnetic properties observed in CeTSi3 (T=Pt and Pd) and superconductivity in LaPdSi3 (TSC= 2.6 K), as well as the theoretical interest in...

One-dimensional (1D) spin chain is interesting to understand the low dimensional magnetism. For a 1D spin chain, long rang magnetic order cannot exists at finite temperature. On...

Materials with layered honeycomb structures have been subject to a strenuous research effort in the past couple of years in an effort to find materials that exemplify the...

Unveiling quantum effects in materials at low temperatures, such as quantum spin-liquid behavior, have been a central task in condensed matter physics. A two-dimensional kagome...

Our recent musr studies on CeT 2Al10 (T=Os and Ru) reveal a clear sign of long range magnetic ordering below 28 K in both the compounds. More interestingly the frequency...

Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it...
