We show experimental results on magnetic phases of Josephson vortices (JVs) in Bi2Sr2CaCu2O2+y, obtained from the JV flow-resistance measurements. Periodic oscillations in the flow-resistance enable us to assign the phase of the long-range 3D ordered state, which was confirmed by the beating effect. We have made preliminary experiments on the doping effect to the JV magnetic phase. The doping effect is reflected not only in the lower boundary of 3D ordered phase, but also in the upper boundary… CONTINUE READING
