(Color online) A PCAR spectrum of a Nb/Er contact at T = 2.3 K and µ 0 H = 0.0 mT, exhibiting spin polarization of 58%.
(Color online) A PCAR spectrum of a Nb/Er junction, measured at T = 2.6 K and µ 0 H = 0.0 mT, consisting of two separate contacts, with relatively low spin polarization.
(Color online) An example of the zero-field temperature dependence of the conductance spectra of the Nb/Er contact of Fig. 4. The normal state conductance of the contact is G n = 354.0(1) G 0.
(Color online) An example of magnetic field and bias anti-symmetric effect on the conductance spectra of a Nb/Er contact at T = 2.4 K. The magnetic field is applied almost orthogonal to the current direction.
