The steps to follow are:
1. Subscription page: they click and they get redirected to PayPal to pay.
2. Upon return from PayPal, they land in a page which contains a link to the magazine pages.
This landing page needs to be a standalone page, meaning that there must not be links to this page from anywhere, otherwise someones, especially search engine crawlers, can find it and then it will become public. Also you need to include a "Nonfollow" tag to show search engines that these pages must NOT be indexed.
Usually this type of sites follow a different approach: subscribers are to be registered. Their info is stored in a database. When the come back from PayPal, a script verifies that they have indeed payed. It automatically updates their member account with an indication that this member has paid the subscription up to date....... The magazine pages have public links, but the pages themselves are protected by a script that looks into the database to see if the member has paid, and if the subscription is valid, and only allows access if these conditions are fullfilled.
