Abstract Manipulating the spin state of thin layers of superconducting material is a promising route to generate dissipationless spin currents in spintronic devices. Approaches typically focus on using thin ferromagnetic elements to perturb the spin

Quantum criticality: Iron aids restoration An exotic quantum state of matter is identified in a new material by researchers in the USA, Switzerland and Germany. Yasutomo Uemura from Columbia University and co-workers observe quantum criticality in a

Knowing whether a quantum phase transition is first- or second-order is crucial for understanding any associated exotic phenomena, but direct experimental evidence has been scarce. Here, Frandsen et al. report first-order magnetic quantum phase trans

The low energy muon (LEM) technique has been used to probe local changes in the dynamical spectrum of thin film polymer samples taking place as a function of the temperature and the implantation depth below the free surface. The studies have been mad

The competition between collective quantum phases in materials with strongly correlated electrons depends sensitively on the dimensionality of the electron system, which is difficult to control by standard solid-state chemistry. We have fabricated su

Low-energy muon spin rotation and SQUID magnetization measurements were performed on proton-irradiated and non-irradiated highly oriented pyrolytic graphite samples. The samples were found to be ferromagnetic above and below room temperature and to i

Muonium centers are readily formed in a wide variety of insulators and semiconductors due to enormous capture cross sections of the unscreened Coulomb potential produced by positive muons. Following the initial capture, different processes of electro

We used the low-energy μ SR technique (LE- μ SR ) to extend our previous studies on the energy dependence of muonium (Mu) states in Si and insulators [T. Prokscha, E. Morenzoni, D.G. Eshchenko, N. Garifianov, H. Gluckler, R. Khasanov, H. Luetkens,
