| Abstract |
We have made a systematic study of the magnetic properties of low doped manganite films submitted to different oxygenation treatments. We have found that oxygenation dynamics depends critically of the strain field in the sample. The TC and the Mr increase as the oxygen content is increased. A decrease of the coercive field of the LSMO-STO films was observed, indicating that annealing treatments increase the oxygen content reducing oxygen vacancies. |

| Abstract |
We use vortex matter in type-II superconductors as a playground to study how different types of disorder affect the long wavelength density fluctuations of the system. We find that irrespective of the vortex–vortex interaction, in the case of samples with weak and dense point defects the system presents the hidden order of hyperuniformity characterized by an algebraic suppression of density fluctuations when increasing the system size. We also reveal that, on the contrary, for samples with planar defects hyperuniformity is suppressed since density fluctuations have a tendency to unboundedness on increasing the system size. Although some of these results were known from previous works, this paper makes the fundamental discovery that the ability of planar disorder to suppress hyperuniformity grows on increasing the softness of the structure for more diluted systems. |

| Abstract |
We used a micromechanical torsional oscillator to measure the magnetic response of a twinned YBa2Cu3O7−δ single crystal disk near the Bose glass transition. We observe an anomaly in the temperature dependence of the magnetization consistent with the appearance of a magnetic shielding perpendicular to the correlated pinning of the twin boundaries. This effect is related to the thermodynamic transition from the vortex liquid phase to a Bose glass state. |

| Abstract |
Magnetic (χ), transport (Ï), and heat capacity (Cm) properties of CeIrSi are investigated to elucidate the effect of geometric frustration in this compound with trillium type structure because, notwithstanding its robust effective moment,
μeff≈2.46μB, this Ce-lattice compound does not undergo a magnetic transition. In spite of that it shows broad Cm(T)/T and χ(T) maxima centered at Tmax≈1.5 K, while a ÏâˆT2 thermal dependence, characteristic of electronic spin coherentfluctuations,is observed below Tcoh≈2.5 K. Magnetic field does not affect significantly the position of the mentioned maxima up to ≈1 T, though χ(T) shows an incipient structure that completely vanishes at
μ0H≈1 T. Concerning the ÏâˆT2 dependence, it is practically not affected by magneticfield up to μ0H=9 T, with the residual resistivity Ï0(H) slightlydecreasing and Tcoh(H) increasing. These results are compared with thephysical properties observed in other frustrated intermetallic compound. |
