Since the first days of high-T c superconductivity, the materials science and the physics of
grain boundaries in superconducting compounds have developed into fascinating fields of …

Magnetic oxides show a variety of extrinsic magnetotransport phenomena: grain-boundary,
tunnelling and domain-wall magnetoresistance. In view of these phenomena the role of …

We comment on both recent progress and lingering puzzles related to research on magnetic
tunnel junctions (MTJs). MTJs are already being used in applications such as magnetic-field …

Complex charge transport mechanisms in disordered systems are often difficult to
characterize owing to a dearth of suitable probes. Non-Ohmic response to an applied …

We present evidence of direct electron tunneling across intrinsic insulating regions in
submicrometer wide bridges of the phase-separated ferromagnet (La, Pr, Ca) MnO 3. Upon …

We report on the use of the colossal magnetoresistance (CMR) effect in manganites for the
measurement of pulsed magnetic fields up to the megagauss limit. To increase the …

A series of coherently strained multilayer thin films of SrTiO 3/L a 2/3 Ba 1/3 MnO 3 have
been fabricated on (100) SrTiO 3 and (100) NdGaO 3 substrates by laser molecular-beam …

Transition metal oxides show fascinating physical properties such as high temperature
superconductivity, ferro‐and antiferromagnetism, ferroelectricity or even multiferroicity. The …

Tunneling electroresistance of Pt/BaTiO 3/SrRuO 3 ferroelectric tunnel junctions is
investigated as a function of temperature. Two distinct resistance states that are dependent …

A series of high-quality, coherently strained [La 2∕ 3 (Ca or Ba) 1∕ 3 MnO 3∕ SrTiO 3]× N
superlattices has been prepared on (100) SrTiO 3 and NdGaO 3 substrates by laser …
