A new type of nanometerscale correlated pinning structure is reported. This structure, consisting of NdEuGd/Ba-rich clusters forms fine lamelar arrays inbetween regular twin planes. The new pinning medium is extremely effective in high fields, shifting inrreversibility at 77 K above 11-12 T (SQUID) or 15 T (VSM, field sweep rate 0.7 T/min).
