A magnetic domain boundary on the surface of a three-dimensional topological insulator is predicted to host a chiral edge state, but direct demonstration is challenging. We used a scanning superconducting quantum interference device to show that curr

After a very brief description of what has been learned from tunneling measurements in conventional superconductors, we provide an overview of general concepts relevant to the cuprates. These include the types of junction structures used, effects due

The SQUID microscope has the advantages of excellent field sensitivity, small interaction between the sensor and the sample, and a linear, easily calibrated response. It has the disadvantages of modest spatial resolution and the requirement of a cool

We have used scanning SQUID magnetometry to image vortices in ultrathin Ba0:9Nd0:1CuO2xm= CaCuO2n high temperature superconductor samples, with as few as three superconducting CuO2 planes. The Pearl lengths ( 22 L=d, L the London penetration depth, d

We have investigated the properties of biepitaxial YBa2Cu3O72d grain boundary Josephson junctions, which appear to be characterized by low barrier transmission probabilities. Extrinsic and intrinsic d-wave effects are discussed within the framework o

A detailed investigation of the magnetic response of YBa2Cu3Ox grain-boundary Josephson junctions has been carried out using both radio-frequency measurements and scanning superconducting quantum interference device microscopy. In a nominally zero-fi

We review some aspects of the physics of high temperature superconductivity (HTS) related to coherent phenomena and unconventional pairing symmetry. We discuss the role of the Josephson effect as a very powerful probe of the underlying physics of HTS

We have measured the angular dependence of the Josephson critical current density (JC) in c-axis tilt biepitaxial grain boundary YBa2Cu3O7 junctions. We observe for the first time intrinsic d-wave pairing symmetry effects manifested as an oscillatory
