| Tunneling condition: Vbias: -100mV, Iset: -100pA. The left image shows a histogram of peak to peak gap values obtained from spatially resolved spectra over a 100nm x 100nm area in Y-123 for H=0,4T. The middle image is a line cut (600 Å long) through two vortices in Y-123 at H=4T. The right image compares spectra inside and outside vortices at H=4T. |
